Description of the invention [Technical field to which the invention belongs] Background of the present invention The invention generally relates to a head-mounted display which displays an image appearing in front of a user. 5 [Previously head-mounted displays may use a liquid crystal display 'placed near the user's eyes to display a virtual image that appears to float before the user. The liquid crystal display can be very small, so it is relatively light and becomes a very portable display system. For example, the image can continue to be viewed while 10% of the user appears to allow the user to move around. This may be useful for assisting with relatively complex tasks such as product mix. Of course, the lighter the head-mounted display can be made, the less the display that produces an image will cause inconvenience to the user. The more the user's movements are hindered by the weight of the display, the less the user will want to use these types of displays. [Summary of the Invention] A general head-mounted display includes a 20 liquid crystal display state before each eye. As a result, three-dimensional or three-dimensional images can be produced. However, the added weight of optical instruments and displays per eye may increase the burden on the user of the head-mounted display. Therefore, there is a need for a 200301826 (2), invention description method that provides a better pair of head-mounted displays with granular images. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a specific example of the present invention; FIG. 2 is a schematic diagram of another specific example of the present invention; and FIG. 3 is a schematic diagram of another specific example of the present invention. . L Embodiment 3 Detailed Description of the Invention Referring to FIG. 1, a head-mounted display 10 may include a liquid crystal display 12. The liquid crystal display 12 may be connected to a suitable processing device not shown 10. Those devices can produce images displayed on the liquid crystal display 12. In some cases, these processing devices may be part of a head mounted display, while in other cases they may be far away from the display. The image produced by the liquid crystal display 12 passes through a liquid crystal display shutter 15, a mirror, and a beam splitter 14. The liquid crystal display shutter of the beam splitter 14 allows an image in one case to pass through the beam splitter 14 and is reflected in the next case. Therefore, when the image is reflected, it may be viewed by the user's right eye as shown in R in FIG. Conversely, when the image is penetrated 20, it can be reflected by the parabolic mirror 16 and viewed by the user's left eye (L in Figure 1). The beam splitter 14 separates a light beam into two separate images, and because of its liquid crystal display shutter, it behaves at different times like this at 200301826. A liquid crystal display shutter system that changes the beam splitter 14
口、J 透射率及/或反射率特性的電子啟動裝置。因此在一情況 下該光束分光裔14係作為一反射器，而在接下來的情況 下該光束分光器14係為一有效的透明。結果，左邊和右 5 邊的影像可以連續地施加到左眼和右眼。如果這連續的交 互影像可以在夠高的速度下進行，它可能不會被使用者注 意0 在第1圖中所顯示之頭戴式顯示器10的結構，結 果使得第二液晶顯示12係不再需要。也就是說，單一液 1〇晶顯示12可以在不同時間點對左眼和右眼的提供不同的 影像或晝面。結果，檢視者會認為他或她正在檢視持續立 體的左邊和右邊影像。左邊和右邊的影像經過光束分光器 14的作用可以連續地且選擇性地被產生提供到左眼和右 眼。 15 結果，在一些具體例中該頭戴式顯示器10的能量 消耗、重量和尺寸可被戲劇性地減少。因為液晶光閘是相 對較輕的，因此增加一個光閘而移除一液晶顯示器會造成 一相當大的重量減少。而且，該液晶光閘可能係實質上比 支曾力σ一液晶顯示器還要便宜。 20 參照第2圖，該顯示器12係依據第1圖所描述 來運作的，然而光束分光器14a只提供一光束分光功能 。在這情況下，液晶光閘18a與18b係各別提供一被使 用者的左眼（L)和右眼（R)所檢視之左邊和右邊影像。 200301826 玖、發明說明 這多少會增加被頭戴式顯示器10a的重量和尺寸。然而 ，它可以簡化光束分光器u的設計。 最後參照第3圖，一頭戴式顯示器l〇b可以含一液 晶顯示光閘20。在這情況下，一由液晶顯示器12所產 生的影像能選擇性地且連續地被分離到左眼和右眼。舉例 來祝，顯示器12的影像可在第一時間點被光束分光器 22反射至鏡子26a以被右眼所檢視，而在下一個時間點 穿透光束分光器22然後被鏡子22反射，以被左眼檢視Electronic starter with J-transmittance and / or reflectance characteristics. Therefore, in one case, the beam splitter 14 is used as a reflector, and in the following case, the beam splitter 14 is effectively transparent. As a result, left and right images can be applied continuously to the left and right eyes. If this continuous interactive image can be performed at a sufficiently high speed, it may not be noticed by the user. 0 The structure of the head-mounted display 10 shown in Fig. 1 makes the second liquid crystal display 12 series no longer need. That is, a single liquid crystal display 12 can provide different images or day-to-day images to the left and right eyes at different time points. As a result, the viewer will think that he or she is viewing the left and right images of the continuous solid. The left and right images can be continuously and selectively generated and provided to the left and right eyes through the action of the beam splitter 14. 15 As a result, the energy consumption, weight, and size of the head-mounted display 10 can be dramatically reduced in some specific examples. Because the liquid crystal shutter is relatively light, adding a shutter and removing a liquid crystal display causes a considerable weight reduction. Moreover, the liquid crystal shutter may be substantially cheaper than the Zigzag sigma-LCD display. 20 Referring to FIG. 2, the display 12 operates according to the description in FIG. 1, however, the beam splitter 14a only provides a beam splitting function. In this case, the liquid crystal shutters 18a and 18b respectively provide a left and right image viewed by the user's left eye (L) and right eye (R). 200301826 发明, description of the invention This will increase the weight and size of the head-mounted display 10a to some extent. However, it can simplify the design of the beam splitter u. Finally referring to FIG. 3, a head-mounted display 10b may include a liquid crystal display shutter 20. In this case, an image produced by the liquid crystal display 12 can be selectively and continuously separated into the left and right eyes. For example, the image of the display 12 may be reflected by the beam splitter 22 to the mirror 26a at the first time point to be viewed by the right eye, and at the next time point the beam splitter 22 may be penetrated and then reflected by the mirror 22 to be left Eye inspection
